摘要

首先

将前向式树重构策略扩展应用于基于Chord的结构型多播树

提出了路径备用机制

该机制为多播树中每个节点预先寻找一条用于快速恢复与多播树连接的备用路径。接着

以路径备用机制为基础

进一步设计基于Chord的应用层多播协议ChordM-FR。仿真结果表明

ChordM-FR协议的多播树重构速度比采用后向式树重构策略的ChordM-SR协议平均快大约2.5倍。

Abstract

Firstly

the proactive policy to ALM tree which is based on Chord DHT was extended and a back-path scheme with which each node pre-calculates a backup path for itself was proposed.When the non-leaf node leaves

all its child nodes can switch to the respective backup path immediately.Moreover

the ChordM-FR protocol which based on Chord and adopts the Back-Path scheme was developed.The simulations demonstrated that the ChordM-FR can reconstruct ALM tree about 2.5 times faster on average than the ChordM-SR which adopted the reactive policy in reconstructing multicast tree.
